Jan Mayn is a part of the same volcanic structure as Iceland. It can be shown by pointing out the pair of convection rolls connecting the highest volcano of Iceland, Öræfajökull, with the volcano of Jan Mayen, Beerenberg.
I have a BS degree in geology, BA in anthropology, graduated in Chinese language and as a certified tourist guide. I provide this website about my contribution to answer the greatest question remaining about our Earth. I have analyzed the convection rolls within the Earth's mantle and how they affect the surface. This makes it possible to provide many interesting examples about geology found on my blog.
